NOVA scienceNOW

is the companion website for a TV show on science breakthroughs and personalities. Learn about a frog that freezes solid in winter and comes back to life in spring. Watch videos about robot "swarms" that work together on a task, a newly discovered system in the brain, tools for predicting a hurricane's intensity, and why some sand dunes burp, sing, and croak. A teacher's guide and transcript are included. The show is hosted by Robert Krulwich and airs five times a year. (WGBH, National Science Foundation)
